Implant dentistry has evolved and come to a full circle regarding the need of bone grafting. In the early years of implant dentistry, bone grafting was extensively used for any bone volume deficiency. Today with the highly successful basal implants, short implants (Bicon implants 5 mm length), pterygoid implants and Zygomatic implants the indications for bone augmentation are no more. For these techniques native or original cortical bone is more than enough. It is not only enough for implant placement but also for immediate loading. (See permanent teeth in 3 days)

Bone grafts have also been used to restore bone contour for esthetic purposes which has now been replaced with very good results with less the invasive connective tissue grafts.

Today it is considered highly preferable to place implants in native or original bone which is more highly mineralized in comparision to grafted bone which is less mineralized (less strong).

As such Block Grafts, Sinus Grafting, and Guided Bone Augmentation are not being used by experts. Techniques like All-on-4 or All-on-6, Teeth in a Day, Teeth in an Hour, Permanent Teeth in 3 days^TM have bypassed or done away with unnecessary bone grafts.
